SPECIFICATION forming part of Letters Patent No. 449,451, dated March 31, 1891.

Application filed November 22, 1890. Serial No. 372,354. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH TRITZ, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Rocking Meat-Cutters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in meatcutters; and it consists in the construction, arrangement, and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the accompanying drawings, in which similar letters of reference designate similar. parts, Figure l represents a side elevation of the frame of a meat-cutter embodying this invention, the knife-bearing bars with the knives being elevated but not thrown back, so as to rest against the crank-wheels, as it should be, in order to support said bars and knives in such position. Fig. 2 represents a plan view thereof with the mechanism attached. Fig. 3 represents a side view of one of the knives detached from its bars and shows means for attachment thereto. Fig. 4 represents a plan view of one of the knifesupporting bars detached. Fig. 5 is a plan View' of the block, showing in black lines the position of the knives in their bars. Fig. 6 is a detail plan view showing the wheels and connections by which the block is adjusted.

Referring to the drawings by letter, A designates the base-frame of the machine, preferably of rectangular shape. This base is suitably supported at its corners or rests upon the floor or other support. From the corners of one end of the frame A rise posts or standards a a', the former having bearings in the tops for the ends of the transverse shaft B, upon which is a pulley and suitable mechanism connecting with the drivingpower for operating the knives. All this being of the usual character in this class of devices, need not now be shown.

C C are crank-wheels upon the ends of the shaft B, and c c are pitmen, pivoted at their outer ends to wrist-pins c on the wheel O O and at their inner ends to pins c2 on the side of the reach-bars D. These bars D are pivoted at their ends to the same pivot-pins F and G on which the upper ends of the arms or bars E and E are pivoted. At their lower ends said bars E and E are respectively pivoted at e and e to the standards a and a of the base, the purpose of which is to retain the bars D in position above and with relation to the block L. The pivot-pins F and G and bars E and E', &c.,are duplicated on the other side of the machine. By means of the crank-wheels Gand the pitmen c the oscillating movement of the knives is effected, as will be fully understood from what has been already said and the further description of this cutter.

.Inside of the bars E E come the knifebearing bars I-I, which are journaled on the side toward wheel O on the pivot-pin F, and at the other end have a recessed bearing to rest on the pivot-pin G. The hook 7L, attached at about the center of the bar II, can be engaged on a pin h upon the bar l), (in like manner on the other side of the cutter,) and thus the bars D and I-I can be locked together when desired, or may be released from each other in order to raise the knife-bars, as for cleaning or sharpening the knives. From side to side of the cutter run the bars I, to which the knives K are secured. These bars are attached at their ends to the bars II, and each of said bars I has the shape shown in Fig. 4. The notches t' in the side of the bar are for the engagement of the upwardly-extending rods 7o of the knife. The upper ends of these rods are screw-threaded, and on these are the upper and lower nuts lo', by means of which said rods are secured to any desired pair of notches t' in the barI and can be adjusted up or down. It is desirable that these knives, which are of uniform length, shall be so placed in these bars that the outer one on each side shall extend farther forward than the one next to it, and the knives so arranged that their inner ends shall be on a semicircle conforming to the shape of the block L. This is all illustratedin Figs..2 and 5. By this arrangement the knives do not cut all the way across the block L, but a IOO curved space toward the front is left to allow room to work the meat and throwY it toward the center.

The block L may be made in any usual or desirable way. As now represented, it rests upon travelers M, which are regulated as to height by means of the Wheels fm, of which there are usually three. These are connected together by a chain m', and thus can be operated simultaneously. This arrangement provides fora chopping instead of a draw out of the knives, which is a great essential in this class of devices. This construction also holds the knives suspended when the block is entirely removed-also a point of considerable consequence. Vhen the knives are thrown up for sharpening, the bars can be made stationary by means of a pin e2 passing through both at their crossing-point.

Having now described my invention, what I claim is l. The meat-chopper having the bars pivoted at their ends to the upper ends of bars or arms, in turn pivoted at their lower ends,

in combination with the knife-bearing bars connected to pivots between the aforesaid bars and adapted to rest at their freey ends upon other pivots between the vlatter bars, substantially as set forth.

2. rlhe meat-chopper havin g the bars adaptbe lifted up and the knives properly exposed.

4. In ameat-chOpper, the combination,with 4o the bars E E', pivoted and adapted to be operated as set forth, of the bars D, having a pin h on the sides, and the knife-bearing 'barsIL having hooks h, whereby the said bars D and H can be locked together when 45 the knives are to be operated or disconnected from each other when desired.

5. In a meat-chopper, as described, the knives K, fixed and adjusted in position, as set forth, whereby the said knives are ar- 5o ranged so that the ends of the outer ones project forward farther than the next ones and through the series, and said ends are thus arranged on thearc of a circle.

In testimony whereof I aix my signaturein 5 presence of two witnesses. p

JOSEPH TRITZ.
